* riginals have been traced with AD712 and NE5532, both of which are still readily
available. No rules here - find the one you like the best. PA2604 are good, but you
may like a nice, simple 2262, 4558 or 072.
** ther FETs may work well, but original uses these.
Wiring shown overleaf will disconnect the battery when you remove the jack
plug from the input, and also when a DC plug is inserted.
Snap the little metal tag off the pots to mount them flush in the box.
You should use some kind of heat sink on the legs of the diodes when
soldering. They aren’t keen on heat. Any more than 3-4 seconds of iron
and they’re toast.
There are multiple pads for G D as well as pads for Jack-I and Jack-
OUT. These are used when combined with a Direct-Connect Daughterboard.
If you aren’t using a daughterboard just ignore J-I , JI, JO and J-OU, otherwise
please refer to the daughterboard document for more details.
The pads for the pots are spaced so
you can use vertical pots if you wish.
Why not try “Cheating Vericals” by
soldering snipped component legs to
the pots as shown left. You can just
wire them normally though.

Test the board!
Once you’ve finished the circuit it makes sense to test is before
starting on the switch and LED wiring. It’ll cut down
troubleshooting time in the long run. If the circuit works at this
stage, but it doesn’t once you wire up the switch - guess what?
You’ve probably made a mistake with the switch.
Solder some nice, long lengths of wire to the board connections
for 9V, G D, I and OUT. Connect I and OUT to the jacks as
shown. Connect all the G Ds together (twist them up and add a
small amount of solder to tack it). Connect the battery + lead to the
9V wire, same method. Plug in. Go!
If it works, crack on and do your switch wiring. If not... aw man.
At least you know the problem is with the circuit. Find out why, get
it working, THE worry about the switch etc.

Wire it up
(if using a daughterboard please refer to the relevant document)
The Board G D connections don’t all have to directly attach to the
board. You can run a couple of wires from the DC connector, one to the
board, another to the I jack, then daisy chain that over to the OUT jack.
It doesn’t matter how they all connect, as long as they do.
This circuit is standard, egative G D. Your power supply should be Tip
egative / Sleeve Positive. That’s the same as your standard pedals
(Boss etc), and you can safely daisy-chain your supply to this pedal.
ow... do some overdriven meditation!

Drilling template

Recommended drill sizes:
Pots 7mm

Toggle Switch 6mm
This template is a rough guide only. You should ensure correct marking of your
enclosure before drilling. You use this template at your own risk.
Pedal Parts Ltd can accept no responsibility for incorrect drilling of enclosures.
It’s a good idea to drill
the holes for the pots
1mm bigger to give
yourself some wiggle
room, unless you’re a
drill ninja.
